Cover art for Afternoon Delight lyrics by Starland Vocal Band

It's about SEX. Read..

"Thinkin' of you's workin' up my appetite Looking forward to a little afternoon delight Rubbin' sticks and stones together makes the sparks ingite And the thought of lovin' you is getting so exciting Sky rockets in flight"

Sky rockets in flight is a guy's dick gettin hard. And pointing up to the sky. This isn't rocket science, it's dick science. If you couldnt see that....then everybody needs help.
